Taxonomic notes
The common name, oakleaf fleabane, is due to the basal leaves being lobed like some oaks.[1]
Description
A description of Erigeron quercifolius is provided in The Flora of North America.
E. quercifolius can be a winter annual, biennial or short live perennial, depending on environmental conditions. Basal leaves have a deeply notched margin, with yellow-green leaves that are rough to the touch. Flower stalks emerge from the center of the basal rosette and can reach about 12-24 inches tall by early summer. The flower heads are small and are composed of many thin, ray petals surrounding a rounded yellow disc [1]. Flowers can be blue, white or pink[2].
Distribution
Ecology
Habitat
E. quercifolius can be found in wetland depressions, wet pinelands, dry turkey-oak pinelands, pine flatwoods, moist open hammocks, and peaty soils of cypress-gum swamps. It is a quick to colonize openings and disturbed areas such as roadsides, vacant lots, open fields, and drainage ditches. Soils include loamy sand, peaty soil, and shell rock. [1][3] Associated species include Helenium pinnatifidum, Parietaria praetermissa, Micromeria brownei, Spermacoce assurgens, Galium hispidulum, Vicia floridana, Commelina diffusa, Rumex verticillatus, Galium tinctorium, Boehmeria cylindrica, and Saururus cernuus. [3]
Phenology
It has an inferior ovary[4] and flowers March through October. [3] Fruits are achenes[4].
Pollination
The following Hymenoptera families and species were observed visiting flowers of Erigeron quercifolius at Archbold Biological Station: [5]
Apidae: Apis mellifera, Bombus impatiens, Epeolus pusillus
Colletidae: Colletes mandibularis
Halictidae: Halictus poeyi, Lasioglossum tamiamensis
Leucospididae: Leucospis robertsoni, L. slossonae
Megachilidae: Coelioxys germana, Dianthidium floridiense, Dolichostelis louisae, Heriades leavitti, Megachile albitarsis, M. parallela, M. petulans
Sphecidae: Bicyrtes capnoptera
Vespidae: Euodynerus hidalgo, Pachodynerus erynnis
Use by animals
It attracts predatory and parasitoid insects that will prey on pest insects. It is a host to thrips and aphids [6]. It is claimed that burning the foliage will chase away fleas and other pests[7].
